Application filed February 9, 1915. Serial No. 7,080.

' To all whom it may concern Be it known that T, GEORGE L. BAXTER, a citizen of the United States of America, residing at 1338 Bryan avenue, Salt Lake city, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Wrenches, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an adjustable wrench and has for its object the production of a simple and eflicient means for facilitating the quick adjustment of the sliding jaw and also conveniently holding the jaw in an adjusted position after the same has once been set.

Another object of this invention is the production of a simple and efficient means whereby the ratchet teeth formed upon the adjustable jaw will be protected by means of the casing adapted to surround the same.

A still further object of this invention is the production of a simple and efficient means for causing the adjustable jaw to be automatically locked as soon as the same has been released. y

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing z-Figure 1 is a side elevation of the wrench. Fig. 2 is a side elevation of the wrench, the locking casing being shown in section, and certain other portions of the wrench being shown in section. Fig. 3 is an enlarged sectional view taken through the lower end of the adjustable jaw and a portion of the handle, showing clearly the action of the spring for throwing the adjustable jaw in engagement with the locking casing. Fig. 4 is a plan view of the blank from which the locking casing is formed.

By referring to the drawing it will be seen that 1 designa-tes the handle which may be provided with teeth formed upon the upper face thereof as indicated by the numeral 2 which may be made straight as indicated by the numeral 3 in Fig. 2 to suit the convenience of the operator. As it is, of course, obvious such changes in construction may be employed without departing from the spirit of the invention.

A locking housing 4 is pivotally secured which casing is formed from of material as clearly illus- .trated 11i Fig. 4 of the drawing. This locking housing 4 comprises a pair of side wings 5. which are adapted to be folded to a position to extend parallel to each other and be to the handle, a blank sheet fpivotally secured at their outer ends to the of a transversely locking casing 4. The lower end Vof the body 7 is bent outwardly to produce a finger engaging lip V12 to facilitate the throwing of the tongue 9 out of engagement with the teeth 13 formed upon the rear face of the adjustable jaw 14.

A pivot link 15 is connected to the adjustable jaw 14 and is slidably mounted upon the handle 1 as illustrated in Fig. 2 of the drawing. The adjustable jaw 14 is provided near the lower end thereof with a socket 16 within which is mounted one end of a coil spring 17 as clearly illustrated in Fig. 8. This coil spring 17 has its outer end bent inwardly between the convolutions of the coil spring as indicated by the numeralV 18, thereby producing a smooth portion for traveling upon the rear face 19 of the handle 1 as illustrated in Figs. 2 and 3.

It should be understood that the adjustable jaw may be operated by pushing inwardly upon the lip 12, thereby causing the spring 17 to be compressed and the tongue 9 to be drawn out of engagement with the teeth 13. This is possible owing to the fact that the adjustable jaw 14 will pivot at the point indicated by the numeral 20, whereas the looking casing 4 will pivot upon the pivot pin 6, thereby allowing the tongue 9 to be drawn out of engagement with the teeth 13 to permit the proper adjustment of the jaw 14.

From the foregoing description it will be seen that a very simple and eiiicient wrench has been produced of the adjustable type, wherein the teeth upon the rear face of the adjustableV jaw may be held out of engagement with foreign objects for preventing `is claimed as new, 1s:-

An adjustable wrench of the class described comprising a stationary jaw, anadjustable jaw slidably mounted thereon, a locking housing carried by said stationary Vjaw and passing around said adjustable j aw and adapted to hold said adjustable jaw in a setposition, said adjustable jaw provided with a retaining link pivotally secured thereto and passing around said stationary jaw, said adjustable jaw provided with a socket near one end thereof, a coil spring fitting in said socket and engaging the rear face of said stationary jaw, the free end of said coil spring being bent inwardly to lit between the convolutions of said coil spring for facilitating the sliding of said coil spring longitudinally upon the rear face of said stationary jaw.

In testimony whereof I hereunto aiix my signature in presence of two witnesses.
